Answer:

<h3>Part A</h3>

<u>4 CD's cost $30.40, so one CD costs:</u>

  • 4p = $30.40
  • p = $30.40/4
  • p = $7.60
<h3>Part B</h3>

80% of the regular price is $7.60

<u>If the regular price is r, we have:</u>

  • 0.8r = $7.60
  • r = $7.60/0.8
  • r = $9.5

<u>3 CD's at regular price cost:</u>

  • $9.5*3 = $28.5

Since $25 < $28.5, we can't buy 3 more CD's.

<h3>Part C</h3>

The mass of the particles that a river can transport is proportional to the sixth power of the speed of the river. A certain riv
Gelneren [198K]

Answer:

v_2 \approx 1.12246\ m.s^{-1}

v_{10}\approx 1.4678\ m.s^{-1}

v_{100}\approx 1.4678\ m.s^{-1}

Step-by-step explanation:

Mass of particles that a river can transport, m\propto\ v^6

where:

v = velocity of river flow

When v=1\ m.s

then the mass transported, m \propto 1^6

<u>When mass is twice:</u>

v=\sqrt[6]{2}

v_2 \approx 1.12246\ m.s^{-1}

<u>When mass is 10 times:</u>

v=\sqrt[6]{10}

v_{10}\approx 1.4678\ m.s^{-1}

<u>When mass is 100 times:</u>

v=\sqrt[6]{100}

v_{100}\approx 1.4678\ m.s^{-1}

Halla la medida del lado de un cuadrado cuya diagonal es de 14 cm​
8_murik_8 [283]

Answer:

The length side of the square is 7\sqrt{2}\ cm

Step-by-step explanation:

<u><em>The question in English is</em></u>

Find the measure of the side of a square whose diagonal is 14 cmd

Let

d ----> the diagonal of a square in cm

b ---> the length side of a square in cm

we know that

Applying the Pythagorean Theorem

see the attached figure to better understand the problem

d^2=b^2+b^2

d^2=2b^2

we have

d=14\ cm

substitute the given value

14^2=2b^2

solve for b

196=2b^2

98=b^2

take square root both sides

b=\sqrt{98}\ cm

simplify

b=7\sqrt{2}\ cm

6TH GRADE MATH: Angel will construct a box in the shape of a rectangular prism. The base area of the box will be 15 square inche
aivan3 [116]

Answer:

<em><u>C</u></em>

Step-by-step explanation:

if h<28

  • its area= 28×28 = 784, but it is greater than 15 sq inches
  • Its volume = 28×28×28 = 21952, but it is greater than 285 cubic inches

hence h must be less than 28 (h<28)

And not greater than √15 ( h<√15)

Thanx
